Jack Klein is a young theoretical physicist turned Wall Street wizard, using chaos theory to beat markets and questioning why he left the life of the mind. Then a flammable hairpiece and irate commuters trigger a bizarre chain of events, collapsing a foreign currency and raising him to the pinnacle of finance. Soon, Jack finds the fluke that brought him stardom sets in motion a crisis that could destroy both him and the global economy. To stave off disaster, the trader must move in realms of money, power and conspiracy, where a media mogul dreams of turning classic literature into video games, Japanese bankers defend samurai legacies and a hedge fund titan thinks he's a Bond villain. Yet it's a brilliant, seductive ex-ballet dancer turned music producer who makes Jack see salvation lies in understanding the choices he's made. But she's made secret and shocking accommodations of her own, and her mystery just adds to a conundrum he can solve only by deciphering...Obscene Gestures of an Invisible Hand.
